Abstract (en)

[origin: EP4177845A1] The disclosure discloses a method and device for generating a digital model. The method includes: acquiring integrated point cloud data of a measured object based on at least one set of measured object images of the measured object; performing mesh processing on the integrated point cloud data with at least two different resolutions so as to obtain at least two mesh models of the measured object; and integrating the at least two mesh models so as to generate an integrated mesh model with multiple resolutions.
